摘要：
Real time and accurate monitoring of milling state is of great significance to improve machining quality and efficiency. As an important monitoring object of machining state, cutting force is limited due to expensive monitoring equipment and inconvenient installation. Therefore, a milling force monitoring method based on spindle current considering tool wear was proposed. The milling force model considering flank wear was established based on the cutting micro element theory, and the milling force model coefficients were calibrated through milling experiments. Then, the relationship between spindle current and milling force was analyzed by theoretical modeling. Based on Taguchi experimental design, the quadratic regression model of spindle current and milling force in milling process was obtained, and the relationship model between spindle current and cutting parameters considering tool wear was obtained. The accuracy of indirect monitoring milling force method based on spindle current was verified by measuring tool wear under different cutting parameters, which provided effective theoretical guidance for actual cutting process condition monitoring. © 2022, Editorial Department of CIMS.
